Reference Voltage - Siemens MICROMASTER 440 Parameter Manual

Issue 01/06
Caution:
Parameter P2000 represents the reference frequency of the above mentioned interfaces. A maximum
frequency setpoint of 2*P2000 can be applied via the corresponding interface. Unlike parameter P1082
(Max. Frequency) this limits the inverter frequency internally independent of the reference frequency. By
modification of P2000 it will also adapt the parameter to the new settings.

Notice:
Reference variables are intended as an aid to presenting setpoint and actual value signals in a uniform
manner. This also applies to fixed settings entered as a precentage. A value of 100 % (USS / CB)
corresponds to a process data value of 4000H, or 4000 0000H in the case of double values.
In this respect, the following parameters are available:

Full-scale output voltage (i.e. 100 % ) used over serial link (corresponds to 4000H).
Index:
P2001[0] : 1st. Drive data set (DDS)
P2001[1] : 2nd. Drive data set (DDS)
P2001[2] : 3rd. Drive data set (DDS)
Example:
P2001 = 230 specifies that 4000H received via USS denotes 230 V.
If a BICO connection is made between two parameters, the "unit" of the parameters (standardized (Hex) or
physical (i.e. V) values) may differ. MICROMASTER implicitly makes an automatic conversion to the target
value.
